BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to furniture such as sofas, convertiblesleepers, chairs, love seats and more particularly, to furniture thatcan be easily assembled and disassembled, and to upholstered furnitureframe.

2. Description of the Related Art

Furniture that can be easily assembled and disassembled is known in therelated art. Examples of such furniture are provided by U.S. Pat. No.4,140,065 issued Feb. 20, 1979 to L. M. Chacon (modular furniture); U.S.Pat. No. 4,165,902 issued Aug. 28, 1979 to R. A. Ehrlich (knockdownupholstered furniture); U.S. Pat. No. 5,678,897 issued Oct. 21, 1997 to3. C. Prestia (ready-to-assemble upholstered furniture); U.S. Pat. No.5,890,767 issue Apr. 6, 1999 to Y. F. Chang (modular sofa); U.S. Pat.No. 6,241,317 issued Jun. 5, 2001 to J. Wu (modular chair construction)and both U.S. Pat. No. 6,367,880 issued Apr. 9, 2002 to A. G. Niedermanet al. and U.S. Pat. App. Pub. No. US2002/0093235 published Jul. 18,2002 on behalf of A. G. Niederman et al. (modular upholstered furnitureconstruction). Such furniture-often referred to as modularfurniture-provides two basic advantages over conventional furniture.First, it is easier to move than conventional furniture. For example,prior to assembly, modular furniture can be readily moved throughrestricted doorways, hallways and stairways whereas conventionalfurniture is often too bulky or heavy to pass easily through restrictedspaces. And second, because it requires less space when disassembled,modular furniture is less expensive both to ship and to store thanconventional furniture. U.S. Pat. No. 6,942,298 issued September 2005 toHarrison (Five-part furniture frame and method of assembly) However,despite its advantages, there are at least two recognized drawbacks ofmodular furniture. First, frames of all named modular furniture are madefrom solid wood and as a result they are heavy, expensive andlabor-intensive. Moreover the named frames don't provide a possibilityto install an unfolding sleeper.

SUMMARY OF THE INVENTION

The present invention is an interchangeable upholstered furniture framecomprising: a seat box frame, having a fabricated metal frame, plywoodfront panel, two side plywood panels; a plywood back frame; a left armframe, and right arm frame. The invention allows for ease of assemblyand makes possible an interchangeable installation of an unfoldingsleeper mechanism or a standard seat without any modifications to theframe. Using of a combination of welded steel-frame and low-trunkplywood reduces frame's weight and cost, providing, at the same time,extra strength
